POSITIVE SHUTTLE-MOTION 'FOR LOONIS.

SPECIFICATION forming part of Letters Patent No. 299,610, dated June 3,1884.

Application filed January 23, 1853. (No model.)

To all whom, it may concern,.-

Beit known that I, FREDERICK K. WRIGHT, a citizen of the United Statesof America, re siding at Homer, in the county of Cortland and State ofNew York, have invented certain new and useful Improvements in PositiveShuttle-Motions for Looms, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention relates to that class of shuttlemoti'ons in which theshuttles are moved through the warp `from opposite sides of the loom bybeing transferred from one arm oper ating from one side ofthe loom toanother arm operating similarly from the other side of the same.

My invention consists of the combination, with a shuttle provided withalongitudinallymovable spring, of carriers located on either side of theloom, also provided each with a spring adapted to grasp automaticallyand alternately and in a like manner release said shuttle, and thuspropel it with the weft back and forth through the warp of the loom, allof which will be fully set forth hereinafter. t

In my` drawings, Figure 1 is a plan view of the shuttle and associatedparts. Fig. 2 is a longitudinal section through the shuttle andcarriers.

Similar referenceletters indicate like parts in both figures.

Referring to the drawings, A is the shuttle, formed preferably of metal,having an opening,

B, to receive a bobbin, which is preferably of the circular form. Ononeside of the shuttlebody is a hinged spring a, to the free end ofwhich is xed a journal-bearing for one journal of the bobbin. The otherjournal-bearing of the bobbin is formed in the oppositewall of theopening B. A set-screw, b, serves to regulate the tension of the springa and increase or diminish the bearing of said spring upon the bobbin.On one side of the shuttle-body opposite to the spring a is formed agroove, c, which follows the curved contour of said side, adapted to"receive a straight spring, d, provided with V or wedge shaped openingsor slots e e. The bottom of the groove c is curve-d, as shown inFig. 2,and forms a rocking or curved base for the spring d to ride over,whereby the said spring has its ends thrown outward when they are forcedtoward the end ofthe shuttlein either direction. Pins f f pass throughthe shuttle-body, and respectively. the slots of the said spring d, andlimit the longitudinal and lateral movements of the latter, as will behereinafter mentioned. 'Ihe ends of the shuttle A are pyramidal orconicalin form to present proper contact-sur faces to the bevel surfacesof certain barbed springs, to be immediately mentioned.

C C are carriers which have enlarged hollow ends, forming sockets forthe ends of the shuttle A. These sockets are provided with slots, whichreceive the barbed ends of springs g g', which barbed ends normallyextend through said slots and within the sockets or recesses of thecarriers. The spring d has a length less than that of the slot in whichit rests, and when moved longitudinally spaces are formed at one and theother of its ends, to receive the barbs of the springs g g.

E is a shaft journaled in the supportingframe of a loom in such alocation as not to interfere with any of the -moving parts, and it isprovided iat its ends with cylinders F F', having cam-grooves t' t" ofthe form shown in the drawings, partly annular and partly zigzag. LeversG G are pivoted at points j j',

which represent some xed parts of the supporting-frame, and their longarms extend to a line which represents the line of motion of the shuttleas it is driven and drawn through the warp. Short arms H H connect saidlevers G G with the carriers, and serve to compensate between theoscillating movement of the former and the reciprocating movement of thelatter. At the ends of the short arms of levers G G are globes, whichfit into the camgrooves t i. The rotation of the shaftE is effected bymeans of a spur-wheel, I, which connects indirectly with the source ofpower, and as said shaft revolves the levers G G vibrate simultaneouslytoward and from the middle of the loom to reciprocate the carriers C C.

The manipulation of the shuttle may be described as follows: Let ussuppose that the carrier G,by its barbed spring,has taken hold of theshuttle by its leithand end-that is to Say, the left-hand end of theshuttle has entered the socket of the said carrier. By this entry thespring cl has been driven to the right by Contact with the end of thecarrier C, and by the pin f drawn iiush with the surface of theshuttle-body on theleft-hand side, the beveled end of said shuttlebodyhas thrown the barbed spring a on the carrier C out, and the latter hasdropped into the space left between the end of the spring d and theleft-hand wall of the spring-groove. The shaft lhnow rotating, moves thecarrier Gto the left, and draws with it the shuttle to its limitin thisdirection, and then returns the same. At the same time, while the leverG is bcing'moved, the carrier C is reciproeated outward and then inwardtoward the right-hand end of the shuttle. rIhe moment that therightvhand end of the shuttle enters the socket of the carrier C the endof the latter forces back the spring d, which, being drawn into the slotof the shuttle-body at its right-hand end laterally by the pin f', whichbears against the inside of the inclined wall of the slot c', causes theopposite end of the spring to throw out of its slot the springeatoh gofthe carrier C at the instant that the spring-catch g of the carrier Ctakes hold of the shuttle on the right-hand side. The carriers nowrecede from each other, and the shuttle is drawn to the right by thecarrier G, through the warp,to its limit of motion on this side. In thismanner the shuttle is caught and. driven, driven and caught, alternatelyon opposite sides.

I have inserted in the specification a brief mention of the mechanismwhich gives motion to the carriers and shuttle; but as it is myintentionto make a new application to cover this arrangement, with improvementsto the same, I reserve a claim to this for the said future application.

I claim-- l. The combination of a shuttle-body formed with a centralopening for a bobbin andalougitudinal groove in one of its sides, andhaving a curved base at the bottom of said groove, with a spring adaptedto move longitudinally to the right and left over the said curved baseat the bottom of said groove7 said spring having slots at its ends, andpins iixed in the shuttle-body across the ends of the said longitudinalgroove passing through said slots, and serving to limit the longitudinalmovement of said spring, and to cause the ends of the same to beretracted within the shuttle-body, sub stantially as described.

2. The combinatiomwith the shuttle, formed as described, and providedwith the spring (Z and means for limiting the longitudinal and lateralmovement of said spring7 of the reciprocating carriers C C', providedwith springs y g', all arranged substantially as set forth.

In testimony whereof I affix my si gnature,in presence of twowitnesses,this 2d day of January, 1883.

FREDERICK K. VRIGHT.
